To all whom t may concern Be it known that I, NICHOLAS LOUVIERE, a citizen of the United States, residing at Union Post Oiiice, in the parish of St. J ames and State of Louisiana, have invented new and useful Improvements in Rice-Harvest ing Machines, of which the following is a specication. A,

This invention is an improved rice harvesting machine for threshing the rice from standing stalks, the object of the invention being to provide an improved machine of this character which is .cheap and simple, which avoids cutting and handling the straw in harvesting rice and which requiresa comparatively slight expenditure of power in its operation.

The invention consists in the construction, combination and arrangement o'f devices, hereinafter described and claimed.

In the accompanying drawings: Figure l is a side elevation of a rice cutting machine constructed in accordance with my invention. Fig. 2 is a plan of the same. Fig. 3. is a transverse sectional view of the same. Fig. 4 is a detail longitudinal sectional view of the harvestingmechanism. Fig. 5 is a yso detail plan of the comb plate and lifting arms.

In accordance with my invention I provide a frame or truck 1 which is provided with rear wheels 2-3 and is also provided with a front aXle 4 on which are wheels 5. The

by a suitable motor as desired. On the in-y ner side of the wheel 2 is a spur wheel 6v which revolves therewith. The wheel 3 has a sprocket wheel 7 on itsinner side. A post 8 rises vertically from the outer side of the truck at a suitable distance from the rear end thereof and is provided at its upper, on its inner side, with a pulley 9. Inclined braces 10 are also provided for the post. On the inner side of the post, near its lower end is a cleat 11. An endless elevator 12 is at the inner side of the truck, near the rear end, and its trunk 13 is provided at its upper end on its rear side, with a discharge spout 14. At the lower end of the trunk, and ar` ranged under the inner side of the truck is a hopper 15 which discharges into the lower end of the trunk.` The driving shaft l5 of the elevators is provided at its outer end with a spur gear 17 which is engaged by the gear 6 of the wheel 2 so that said elevator is v driven by power from said wheel 2.

The rice threshing mechanism is mounted on a frame 18 which is arranged at the inner side ofthe truck and is pivotally connected thereto as at 19 so that the threshing mechamsm may be extended fhorizontally from the inner side ofthe truck or may be turned y j upwardly to a vertical position, and ar-k ranged over the truck so as to be out of the waywhen the machine is moved from place to place. At the front side of said frame 18 is a plate 20 which -is provided 'at its front.

side with comb teeth 21. At the rear of the comb plate is a horizontally arranged feed trunk 22, which is semi-tubular and open at its upper side and in which operatesafeed screw 23. At the outer end of the feed screw and the said bars are provided with outi wardly extendingl thresher teeth 29.

The thresher cylinder thus constructed is adapted to revolve over the comb plate so that as the machine is drawn forwardly the rice stalks are caught between the comb teeth and the thresher teeth ymove rearwardly through the heads of the rice and strip and thresh the same from the rice stalks and sweep the grains' rearwardly into the conveyertrunk, the screw in the conveyer trunk delivering the grain to the hopp'erfwhich feeds the same to the elevator. An attendant, on the truck causes the grain discharged by the elevator to be caug rtin sacks.

The thresher shaft is provided near its' inner end with a sprocket wheel 3() which is connected by an endless sprocket chain 3l to the sprocket wheel 7 on the drive wheel 3, and hence the`thresher cylinder is driven through directly from 'said drive wheel 3. At the outer end ofthe thresher shaft is a sprocket wheel 32 whichis connected by an endless sprocket .chain in the wheel 24 of said Vso cross bar of the frame 18. A suitable casing 35 is provided for the threshing mechanism and includes a hinged cover 36, which is hinged or pivotally mounted at its rear side as at 37 so that it can be swung rearwardly to uncover the threshing mechanism when desired. To raise and lower the threshing mechanism l provide a suitable cord or rope 38 which is attached to the frame 18 as at 39 and passes over the pulley at the upper end of the post. When the thresher mechanof the plate and a feed trunk in the rear pory tion of the plate and having a spout at its inner end arranged to discharge directly into the elevator, a revoluble threshing cylinder mounted above the plate, means to operate said cylinder, a conveyer screw arranged in the feed trunk, and means to operate the said screw.

2. ln a rice harvesting machine, a horizontally arranged plate, comb teeth at the front side of the plate, a revoluble threshing cylinder mounted above the plate and lifting arms extending downwardly and forwardly from the plate and having their upper ends curved rearwardly and downwardly and attached to the plate at the rear ends of the comb teeth, the upper, curved portions of the said teeth being above said plate.

3. In a rice harvesting machine, a frame, a horizontally arranged plate secured on the frame, comb teeth at the front side of the plate, a revoluble threshing cylinder mounted above the plate and lifting arms extending downwardly and forwardly from the plate and having their upper ends curved rearwardly and downwardly and attached to the plate at the rear ends of the comb teeth, the upper curved portions of the said teeth being above said plate and braces under the comb plate, in line with the lifting arms, having their rear ends attached to the frame, said braces extending forwardly and downwardly and having their front ends attached to the liftingv arms.

4. In a rice harvesting machine, a truck, an elevator mounted on the truck, a frame carried by the truck and projecting from one side thereof, a substantially horizontal plate l on said frame and provided at its front side with comb teeth, a conveyer, at the rear side of said plate, also carried by said frame and arranged to discharge into the elevator, a revoluble threshing cylinder mounted above the plate, means to operate the threshing cylinder, and means to operate said conveyer.

5. InV a rice harvesting machine, a truck, an elevator mounted on the truck, Va frame carried by the truck and projecting from one side thereof, a substantially horizontal plate on said frame and provided at its front side with comb teeth, a conveyer, at the rear side of said plate, also carried by said frame and arranged to discharge into the elevator, a revoluble threshing cylinder mounted above the plate', means to operati the threshing cylinder, means to operate said conveyer, and lifting arms extending downwardly and forwardly from the plate and having their upper ends curved rearwardly and downwardly and attached to the plate at the rear ends of the comb teeth, the upper curved portions of said lifting arms being arranged above the plate.

6. ln a rice harvesting machine, a truck, an elevator mounted on the truck, a frame carried by the truck and proj ecting from one side thereof, a substantially horizontal plate on said frame and provided at its front side with comb teeth, a conveyer, at the rear side of said plate, also carried by said frame and arranged to discharge into the elevator, a revoluble threshing cylinder mounted above the plate, means to operate the threshing cylinder, means to operate said conveyer, the said frame being pivotally connected to said truck for vertical angular movement and said truck being provided with means for raising and lowering said frame.

v In testimony whereof I aiix my signature in presence of two witnesses.

NICHOLAS LOUVIERE.
